Abstract
Patente de Invenção: "MéTODO DE CANCELAMENTO DE INTERFERêNCIA BASEADO EM ANTENA INTELIGENTE". Esta invenção revela um método de cancelamento de interferência baseado em antena inteligente, o qual pode resolver várias interferências em um sistema de comunicação móvel, tal como uma propagação de percurso múltiplo, etc., enquanto usa uma antena inteligente. Ele compreende: com uma matriz de formação de feixe, fazer uma formação de feixe para um sinal de saída de um receptor, com base em uma antena inteligente, então, obter um conjunto de sinal digital NR~ k~(m); cancelar o sinal de percurso principal de outros usuários incluído em NR~ k~(m), então, obter um outro conjunto de sinal digital NS~ k~(m), o qual inclui apenas o sinal necessário e todos os sinais de interferência; pesquisar no sinal digital NS~ k~(m) e obter todos os sinais de interferência de percurso múltiplo que vêm de outros usuários; cancelar outros sinais de interferência de percurso múltiplo em NS~ k~(m); sobrepor o percurso principal de usuário e cada sinal de percurso múltiplo em coincidência de fase, então, obter um sinal digital com a interferência cancelada.
